Abstract

The invention discloses an atomic clock frequency and phase adjustment device. The atomic clock frequency and phase adjustment device includes a first isolation distribution amplifier, a frequency multiplier, a frequency integration module, a frequency divider, a frequency mixing unit loop filter and a high-stability crystal oscillator. The invention further discloses a high-resolution frequency detection device and a high-resolution phase detection device. According to the atomic clock frequency and phase adjustment device, frequency detection device and phase detection device of the invention, a homologous comparison method is utilized to perform post-frequency and phase adjustment comparison on the frequency and phase adjustment device and an HROG-5 type frequency and phase adjustment device, so that high-resolution frequency and phase detection can be completed.

Description

technical field [0001] The invention relates to a frequency and phase detection device, in particular to an atomic clock frequency and phase adjustment device and a frequency and phase detection device comprising the above device. Background technique [0002] The basic equipment of the timekeeping system is the atomic clock. Although the time-frequency reference provided by the atomic clock has very high frequency accuracy and frequency stability, due to the aging of the components of the atomic clock and the change of the ambient temperature, it has the characteristics of long-term drift rate, and Once the atomic clock used for timekeeping is working, it is not allowed to be adjusted again. In this way, although the atomic clock for timekeeping has excellent frequency characteristics, the cumulative error of timekeeping will continue to increase with continuous operation for a long time. [0003] The high-precision frequency and phase adjustment device is an indispensable ...
